indication

For the treatment of anorexia associated with weight loss in patients with AIDS, and nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments

pharmacology

Marinol may has complex effects on the central nervous system (CNS), including cannabinoid receptors. Dronabinol may inhibit endorphins in the emetic center, suppress prostaglandin synthesis, and/or inhibit medullary activity through an unspecified cortical action.

mechanism of action

The mechanism of action of marinol is not completely understood. It is thought that cannabinoid receptors in neural tissues may mediate the effects of dronabinol and other cannabinoids. Animal studies with other cannabinoids suggest that marinol's antiemetic effects may be due to inhibition of the vomiting control mechanism in the medulla oblongata.

biotransformation

Hepatic

absorption

90 - 95%

half life

Alpha phase: approximately 4 hours; Beta phase: 25-36 hours

route of elimination

drug interactions

Trimethobenzamide: Anticholinergics, such as Trimethobenzamide, may increase the tachycardic effect of cannabinoids such as Marinol. Close monitoring of cardiovascular effects is recommended.

Trospium: Anticholinergics, such as Trospium, may increase the tachycardic effect of cannabinoids such as Marinol. Close monitoring of cardiovascular effects is recommended.
